Is there any work around to report the validation to the Problems view, I have a scenario where I need to validate an xml based on a schema and report the problems to the Problems View, I have modeled my Sapphire Model classes based on the XSD. Fro your previous post i see there is a Open Bug reporting the messages to Problem view

This isn't really a workaround, but one could certainly write a custom builder that looks for files you are interested in, uses your model to validate those files and then exports the results as resource markers. You would in effect be implementing a non-general version of the builder that's tracked by Bug 329080.
